nonceTPM

public byte[] nonceTPM

the policy nonce for the session This can be the Empty Buffer.

cpHashA

public byte[] cpHashA

a reference to a policy relating to the authorization may be the Empty Buffer Size is limited to be no larger than the nonce size supported on the TPM.

expiration

public int expiration

time when authorization will expire, measured in seconds from the time that nonceTPM was generated If expiration is non-negative, a NULL Ticket is returned. See 23.2.5.

auth

public TPMU_SIGNATURE auth

signed authorization (not optional)
